The Peter Iwers series is a signature line of solid body electric bass guitar models offered by Ibanez. It is the signature series of Swedish bassist Peter Iwers who is known primarily for his work with the Swedish heavy metal band In Flames.
Iwers' first signature bass from Ibanez, the PIB1, was released for 2009. It was a five string bass with neck-through-body construction based on the Soundgear series. Two more models were added before the series was discontinued after 2017.
